SAN BERNARDINO, Calif. – A California sheriff has placed 10 deputies on paid administrative leave after news video recorded a violent arrest that he says appeared to be excessive force.

San Bernardino County Sheriff John McMahon announced the action in the aftermath of the arrest of 30-year-old Francis Pusok, who fled by car and then on a stolen horse when deputies tried to serve a search warrant in an identity-theft investigation Thursday.

McMahon says an internal investigation has begun on the use of force. In addition, two criminal investigations have begun — one into Pusok's actions and the other into the deputies actions.

The sheriff says he was "disturbed and troubled" by what he saw in the video recorded by a KNBC-TV helicopter crew.
